Power of Attorney

My wife has Power of Attorney for her mother. Her half sister is on the papers only if something happens to my wife. Can my wife change the locks on her mother's house and tell her sister to return her mothers car? The sister is doing what she wants and not recognizing. My wife's Mother is in a nursing home after a stroke.

I am selling my timeshare which is located in Arizona through a title company located in Florida and have been asked to sign a limited power of attorney so the 'agent' can act on my behalf in the transaction. The form I have been asked to sign grants the agent powers 'including, but not limited to, the power and authority to execute any instruments necessary to close the transaction and to allow the agent to act in my stead at the time of closing.' I AM CONCERNED BY THE PARENTHETICAL 'BUT NOT LIMITED TO.' Should I be concerned?

Is there a way to fight a power of attorney if you believe it was done to gain access to an elderly family members money?

What is a 'qualifying Power of Attorney' as it pertains to bail bond?

My 2 sisters and I are all beneficiaries to my fathers estate, who passed away 1yr ago. It was not until after he died I found out they took him to another attorney and had him make them Power of attorneys, I also found out after his death, they took him to a bank, and had him take a loan against his house that had no mortgage, for $100,000, he was 86, it was a 30 year loan no co -signers ( they lived and still do live in his house along with 1 of their husbands) never payed any bills, my father payed everything, and yes they all work, they would write ck from his checking account and have him sign them, I always thought they helped pay the bills, They want to buy my share of the house out but their lawyer and them tell me I am responsible for 1 3rd of the loan because it was my fathers loan, and they fixed up the house with it, they also drained his entire bank account. about $200,000..by the way my father was dignosed with moderate dementia before they did any of this... Help what can I do? By the way, the lawyer they took him to to get them to be Power of attorney is now their lawyer. Help I have a lawyer, I just want to see what action you would take...not only the loan, but what else I can do ?
